Description
CATO manufactures Bromhexine Impurity 8 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Bromhexine Impurity 8 (CAS 1660957-78-7), a pharmacopoeial impurity reference standard (molecular formula C13H18Br2N2HCl, MW 398.57 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Bromhexine Impurity 8 (C13H18Br2N2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
